Bostich pass thru sockets at Wal-Mart

I was in Wal-Mart today and saw a set of Bostich pass thru sockets on the shelf. It was a 21 piece set and covered 10-19mm and 3/8-3/4 S.A.E.
Here is a link to Bostich. http://www.bostitch.com/default.asp...%2D+Piece+Pass+Thru+Socket+Set+%283%2F8%94%29

The tools looked ok for Tawain built, they were $39.99. There was only one set on the shelf. I didn't buy them but they may be useful.
Harbor Frieght has a simular set for $20.00. I am interested in pass thru sockets but wish there were longer extensions availible for them.
They also had a couple of 3/8" square drive ratchets. I didn't check the price on them.

Looks much like the HF set.

Look at gearwrench/craftsman. They are interchangeable and have a 6in extensions and a 12in extension. More expensive than HF, but very nice chrome, finish, etc.
